To all whom it may concern:

Be it known that I, SIMON P. Com, a citizen of the United States, residing at Dickinson, in the county of Stark and State of North Dakota, have invented certain new being cured by reducing the pressure of the and useful Improvements in Cut-Outs and auxiliary reservoir, the branch pipe may be Releases for Air-Brake Apparatus, of which closed, thereby cutting out the brake system. the following is a specification, reference It will be understood of course that in the being had therein to the accompanying practical application of the invention, the 3 drawing. same is susceptible of a wide range so far as This invention relates to air brake systems, detail and structural arrangements are conand the principal object of the same is to cerned, but a preferred and simple embodiprovide means whereby the brake system of ment of the same is shown in the accoma car may be controlled so that its pressure panying drawings, wherein 7 may be reduced, or the system of the car Figure 1 is a perspective view of a porcut out without the necessity of stopping the tion of a car floor shown broken away to car. illustrate the application of the present in- The invention is an improvement on my vention to the brake system. Fig. 2 is a de- Patent No. 943,769, issued December 21, tail fragmentary view in side elevation of 1909. In said patent, means are provided the pressure reducing device. whereby the supply from the service pipe Referring to said drawings by numerals, 1 may be cut off and the pressure in the auxdesignates the floor of a car, 2 the service iliary reservoir reduced simultaneously by pipe that extends longitudinally beneath the means of a rod that ext nds into the car so same. A branch pipe 3 connects the service 30 that the operation of cutting off the supply pipe 2 with the triple valve chamber t, and and reducing the pressure of the auxiliary has the usual communications with a brake reservoir can be performed by a trainman cylinder 5, and auxiliary reservoir 6 So on the car without the necessity of stopping far as described, the air brake system is the the car. As explained in said patent, the same as in common use. The branch pipe 30 mechanism covered thereby is for the pur- 3 is equipped with a controlling valve 7, as pose of cutting out the brake system of a is shown in my patent mentioned in the ear in the event of the system developing foregoing, said valve having a controlling dynamiting tendencies, and, obviously, by rod 8 projecting therefrom, that extends into operating the same, the system of the car a cup 9 seated in the floor 1 and has a 35 will be cut-out. It has been found howsquared end so that said rod may be grasped ever, that in some cases a dynamiter may by the hand or by a turning tool to rotate be cured by reducing the pressure of the the rod, and thereby operate the valve. auxiliary reservoir without entirely cutting cover 10 is provided for said cup, said cover out the brake system, and to provide a conand the upper portion of the cup being flush 40 trolling mechanism for performing this with the upper surface of the floor-1. A refunction, is the primary object of this inlease pipe 12 projects from said reservoir 6 vention. and has its outer end equipped with a valve In carrying out the invention as generally or cook 13 that is preferably located beneath stated above, it is contemplated providing the cup 9, and has an elongated operating 45 the auxiliary reservoir with a valve constem 1 1 that projects into said cup and is trolled discharge pipe, the valve of which equipped with a flattened handle 15. is located beneath the floor or platform of As will be understood from the foregoing, the car and the operating stem of the valve valve 13 may be opened by manipulating projecting into or above the floor or platthe stem 14: to reduce the pressure of reser- 50 form so that the valve may be readily mavo-ir 6 in the event of the brake system develnipulated without the necessity of the trainoping dynamiting tendencies, this operation man leaving the car. As an adjunct to the being performed from the car. And if the same, means are provided whereby the reduction of the pressure does not cure the defect in the brake system, the branch pipe may be closed by manipulating valve through rod 8, thereby cuttmg out the sysbe closed to cut off comthe service pipe to the said munication from triple valve and aux liary reservoir,

What I claim as my invention is:

1. A controlling device for the air brake system of a car, comprising a pipe having one end connected to the auxiliary reservoir, a valve carried by said pipe, and means operable from within the car for controlling said valve.

2. In an air brake system, the combinaand be operated from a car,

n a pressure operated brake system for cars, the combination With the car, the auxiliary reservoir and the branch pipe, of a valve controlled projecting from said reservoir, means ope able from the car for controlling said valve, a valve for said branch pipe, and independent means operable from the car for controlling the valve of the branch pipe.

at. A controlling device for the air brake system of cars, comprising a pipe carried by the auxiliary reser oir, a valve at the outer end thereof, and an elongated stem for said valve projecting into and operable from within a car.

5. In a pressure operated brake system, the combination with the auxiliary reservoir and the branch pipe, of a release pipe for said reservoir, a valve carried thereby, a stem for said valve adapted to project into a valve for said branch pipe, and a rod carried thereby and adapted to project into and be operated from said car.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
